LINE-CASTING MACHINE.

Specification of Letters Patent.

Application filed April 15. 1909. Serial No. 490.170. v

To all wlzom it may concern:

Be it known that I, DAVID S. KnNxn'nY. of the'borough of Brooklyn,county of Kings, and State of New York, have in vented a new and, usefullmprovement in Linc-Casting'Machines, of which the following is aspecification.

' This'invcntion has reference to line castm machines, in whichthemolten metal is delivered by a pump mechanism through the mouth ofthe melting pot into a slotted mold, closed *temporarily at the front bya composed line of matrices whichiorm type characters on the edge of theslug formed in the mold, as shown, for example, in Letters Pa-tent ofthe United States to Mergenthaler No. 436,532. chines, the flattenedmouth of the pot is v advanced temporarily .against the back of the moldto close the same, the pot being retracted after the casting action. 'Inpractice it is found that'there is a tendency of the molten metal, oxid,or other foreign matters to accumulate on theface of the pot mouth, insuch manner as' to prevent it from forming a close contact with themold.

The-Ebject of this invention'is to provide for a )ositive and effectivewi ing of the face of the pot mouth while it 1s separated from the mold,and to this end it consists in a vibratory wiper, arranged to traversethe pot mouth and actuated positively in the general manner hereinafterdescrlbed. In the drawing I haveshown my invention in a form applicableto'commercial lilergenthaler machines made under the patunder the trademark ,Litiotype.

out above described, and generally known Figure l is-a perspective viewlooking from the rear toward the left-hand corner of the machine,with'my improvement applied thereto, showingonly such parts as arenecessary-toan understanding of my invention. Fig. 2 is a frontelevation of the parts shown in the preceding figure.-

. Referring to the drawings,---A represents portions of the main frameof the machine; B the melting pot, supported on legs and arranged toswing forward and backward to an from the mold; E the vertical wheel inwhich the slotted mold is mounted; and 8 an upright lever acting throughlink 8 to' actuate a slide, S, by w ich thecomposed lin. of matrices istransferred from the first cle\ 11101 of the machine to the second ele-In these inatends through a longitudinal form of a notch.

7 After the a subsequent to the casting action, the lever 8 moves to theleft, as usual, to effect the earlier part of the movement of the.mitted to fall slightly,

transfer lever, formsa part of all commercial Mergenthaler machines andis well known to those skilled in the art.

The foregoing parts may all be constructed and arranged to operate asdescribed in the patentabove referred to, or as in the Patented Mar. 22,19 116 vator. The lever 8 commonly known as the Linotype machines nowcommonly known.

to commerce, the parts S, s and s corresponding to the parts indicatedby letters in the patent above referred to.

In applying my invention, I provide'a wiper arm, C, carrying at itslower end a pad or wiper, 0 of felt, wire cloth, asbestos, or othersuitable material. I connect this arm at its upper end to the main frameb a horizontal ivot,'c,' in such position that itslower en' may swinglaterally across and against the mouth of the pot, B in the mannerindicated'in Fi 2.

To the transfer lever s D, by means of a pivot,.d. This link is exthesame connect a link,

tcnded across the face of the wiper arm and connected-thereto by a'stud,0 which exslot, (1 in the link. The slot through which is carrieddownward at the outer end 1n the The lower. edge. of the link D ridesupon a stud, d fi-xed to'the main frame. The under sideof the link isformed near its outer end with a notch or indentation, d

The parts stand normally in, the position shown in Fig. l, with thewiper arm clear of the pot and sustaiinedby the link D, which is in'turnsustained by the stud d".

pot is separated from the mold,

transfer of'th'e matrix line, and

in so doing it carries with it the link D.

During the link the stud asses the stud 0 travels in the straightportion of the slot (1 and the wiper remains unmoved.

When the link has advanced far enough to bring the notch d over the studd, it is perand at the same'moment the wiper arm falls until its stud centers the notch at the end of the slot (P, as shown in Fig 1 2, so thatthe continued movement of the nk to the left causes the wiper to swingentirely across the face of the pot. Immediately following this action,the lever .9 moves back toward its first position, carrying with it thelink. which causes the the Wiper, as is demanded by the fact that v thelever 8 must necessarily receive a mot ion wiper arm to again traveisethe pot and to resume its first position, shown in F 1g. 1, the linkeontmning lilS motion independently of longentlnen that required toactuate the wiper.

It will be observed that serves not only to movetie wip'er positivelythe slotted link E in both-directions, but also to holdit in an Ielevated position beyond the pot when the latter is advancing a ainstthe mold.

It will of course wiper must be actuated at a particular time,

' that'is to say during the temporary separation of the pot and themold, and with my SPGCIZL]. construction and arrangement of heunderstood that the parts I am enabled to effect this movement by meansof the transfer lever, although the latter has a motiongreater than thatrequired onv the part of the Wi per.

Having described my invention, what I claim is:

1. In a, line casting machine of the type described, amold carryingwheel and a pot essence driven member of the machine, substantially asShown; whereby the wiper is carried positively across the mold in bothdirections, and held positively beyond the mold.

:2. In a Mergenthaler line casting machine, the eombiinition of themelting pot, the wiper nrm mounted on a fixed pivot and arranged totraverse the month of the pot, the line transfer lever. and a connectinglink between the lever and the wiper, said link having a limited motionindependently of the wiper, whereby the wiper is moved posi lively inboth directions' and held nm'inally clear of thepot month.

3. in a line casting machine, the combination of the swinging wiper, theactuating lever 8, the intermediate link, slotted and notched, and asupport, d. for said link.

4-. in a line casting machine, the combination of the lever .8 with alink, I), having the slot (Z and notch (2", a link support, (i and apivoted wiper arm, 0, having it stnd seated in the slot of the link.

In testimony whereof 1 hereunto set my hand this 11th day of March,i905), in the presence of two attesting Witnesses.

DAVID S. KENNEDY.
